RAL colour

A RAL colour refers to standardised colours from a colour collection that has been authoritative for colour selection for over 85 years and is distributed by RAL GmbH under the name RAL Classic.

Each colour in the colour catalogue is assigned a four-digit colour number. The first digit is systematic: 1 - yellow, 2 - orange, 3 - red, 4 - violet, 5 - blue, 6 - green, 7 - grey, 8 - brown, 9 - white/black shades, and the remaining three digits are chosen sequentially.

For a surcharge, almost all products, such as timber windows, timber-aluminium windows, aluminium windows, roller shutters and external window sills, can be produced in a RAL colour of your choice.
